SEECIFICATION forming part of Letters Patent No. 695,244, dated March11, 1902.

Application led May 20,1901. Serial No. 61.026. (No model.)

To @ZZ whom, it may concern:

y Be it known that I, HARRISON L. SrALnY, a citizen of the UnitedStates, residingat Martinsville, in the county of Morgan and State ofIndiana, have invented certain new and useful Improvements in Gearingfor Washing-Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to the means for operating Washing-machines inwhich there are parts partaking of rotative motions and also verticallyreciprocatory motions, the objects of the invention being to providesimple and compact gearing for washing-machines which may be cheaplyconstructed and be durable and economical in use.

The invention consists in the novel parts and in the combination andarrangement of parts, as hereinafter particularly described, and pointedout in the claims.

Referring to the drawings, Figure l represente a central verticalsectional view of a Washing-machine and a side elevation of theoperating mechanism constructed substantially in accord with myinvention; Fig. 2, a transverse sectional view of the inner andoutervertical gearing-spindles; Fig. 3, afragmentary view in elevation,showing the front part of the dual-reciprocating-motion gear 5 Fig. 4.,a fragmentary elevation view of a portion of the gear-frame; Fig. 5, atop plan view of the complete gear upon a machine; Fig.

6, a bottom plan view, on a reduced scale, of the rubber and poundercombined to which my gearing is applied and also illustratingsubstantially a top plan of the bottom of the tub; Fig. 7, a perspectiveview of the rotator for moving the articles that may be acted upon inthe tub, and Fig. 8 a fragmentary top plan View of the combined rubberand pounder.

Similar reference characters in the several figures of the drawingsrefer to like parts.

In explanation of the operative functions of iny invention vI show asuitable tub A, having a tight bottom A', preferably provided withradial ribs a or with a cover of corrugated metal. The tub has a lid Bextending nearly over the whole top of the tub, the remaining portionbeing covered by a smaller like part B', which is attached to the tub,hinges (l connecting the parts B and B", so that the lid part may beraised at will, and this preferably has a latch h of suitable form.

A frame-base C is secured to the top of the `lid B, and it has erectedthereon a suitable balance-wheel 71 ,(or a crank-amm) having av handlet', is secured to the outer overhanging end of the shaft F, whereby tooperate the gearing. At the inner end of the shaft F a bevel-gear ortoothed Wheel G is secured thereto, the shaft having a guide-pin jattached thereto projecting beyond the geara Wheel centrally with thecenter of the shaft, of which the pin is preferably a part reduced indiameter.

The base O comprises also a` journal-bearing C', having a suitableaperture to receive a vertical rotative shaft, and the head E islikewise designed for a companion journalbearing for such shaft, and theframe as a whole comprising the parts O C D E e may be made in anysuitable number of separate sections for convenience in assembing themechanism, as Will be obvious. In the lid B is a suitable aperturecorrespondingto the aperture in the bearing OC In the frame-bearings isa vertical spindle or shaft H, having a circular exterior and smooth, sothat it may move longitudinally as well as rotate inthe bearings. In theupper end of the shaft are suitable screw-threads into which is fitted ascrew-threaded rod K, having a detachable lever-handle u. The shaft H ishollow throughout, the portion below the screw-threads being square orrectangular in cross-section, and in this part is slidingly fitted aninner shaft J, having a crosssectional area corresponding to theinterior of the spindle H, so that when the latter rofates it willrotate the shaft J. Obviously this is illustrative rather thanarbitrary,I as a IOO spline may be employed in lieu of the rectangularforms for the purpose. The shaft J is connected at its upper end to thescrew-rod K by means of a T-head t, attached to the end of the rod andinserted into a suitable slot in the shaft J. '..lhe lower end of theshaftJ has a foot w, to which is secured a suitable combined rubber andpounder L, having radial ribs v at the under side thereof or a layer ofcorrugated metal and havin-g also a number of apertures y.

A rotator M, comprising a plate having projecting pins N, is mountedupon the rubber L, the pins inserted in the apertures y and projectingtherethrough. The plate has acentral aperture p, through which the shaftJ extends, this shaft having a stop-pin q or a suitable shoulder toprevent the rotator L from rising above a prearranged distance above thepounder L.

Having illustrated and explained such elements as my invention isdesigned to operate with and also minor parts included in my invention,I will now describe the principal elementin my improved gearing, asfollows: Attached to the spindle H intermediately of its kends orforming an integral part of the shaft is a dual-reciprocating-motiongear engaged by and operated by the toothed wheel G. This dual-motiongear is employed for imparting from the rotative motion of the shaft Fto the spindle II intermittent oscillatory and reciprocatory motions,which are thereby transmitted to the rubber and pounder and to therotator above described or to other suitable devices that may beemployed in churns and ice-cream freezers and the like. The dual-motiongear comprises a body portion having at the upper part thereof a segmentI of a bevel-gear or toothed wheel,y

and having at the lower part thereof a segment I2 of a bevel-gear ortoothed wheel, each having'teeth 7c facing the teeth of the oppositeysegment and meshing with the teeth of the wheel G. At one side of thebody are two reversed lsegments of bevelgear or toothed wheels I and I3,respectively, having also teeth 7a arranged l so that these are segmentsof internal gear-wheels and forming continuations of the segments I andI2, connecting one with the other at two parts of each, so thata toothedWheel meshing therewith may travel continuously in contact with theseveral segments, rolling about the axis of the shaft H in' onedirection, then longitudinally of the shaft, then about it in theopposite direction, and then again longitudinally thereof; but inpractice in the present case the axis of the wheel G is stationary,while the segmentary gears partake of the reciprocatory oscillatingmotions. In the body of said segmentary gear is a continuousguide-channel Z, corresponding in direction to the contour of thepitch-line of the segmentary gear-teeth, the channel extending about theaxis of the shaft H as two parallel branches with a rib m between themand connected at their ends by a guide-pin r and from the opposite sidea like pin r; but these pins may be attached either to the segment I ortoV the spindle H, and they are designed to form contact with avertically-disposed guide-bar n, attached to the gear-frame D, althoughin some cases these pins and the guide-bar may be dispensed with. Y

In practical use let it be supposed that the articles to be Washed areplacedA in the tub with the washing liquid and the relative position ofthe spindle H is at its lower limit of travel, as indicated in Fig. 1,the rubber L having been depressed upon the articles with a suitablylight degree of pressure by means of the screw-rod K, the rotator M.being Lby this action pushedjup to the position shown. Now if the wheelor crank-arm h be put-in motion in the direction of the arrow the partsJ, H, K, L, and M will bevmoved rotatively,

the part L performing the rubbing operation j until they wheel G hastraversed the segment I and vcome in contact with the segment I, whenthe parts J K L will by said contact be elevated, While the pins Ndrop-through their apertures as the part L rises and engage the clothesor articlesin the tub. Immediately before these parts and the segmentIrises by the action of the wheel G the pin r will have passed under thebar n, so that as all the parts rise the pin may engage the oppositeside of the bar and prevent disengagement of the gear-teeth. When theparts described have risen until the wheel G comes in contact with thesegment 12, a reversed rotary motion will begin and the pin R will havereached the top of the bar n and passoverit on the return motion, and inthis reverse movement the pins N will rotate the clothes against therubbers or ribs a. When the Wheel G shall have traversed the segment I2,it will come in contact with the segment I3, the pin r' passing abovethe bar n and then down the side thereof seen in the View in Fig. l asthe segment 13 is forced downward, together with the parts H J K L,until the segment I2 comes into action, when the several positions ofthe parts Vas shown in Fig. l will have been again reached. In itsdownward movement the part L acts as a pounder and also Vas a piston tosuch extent as to force the washing liquid through the articles in thetub, and

likewise the liquid will be sucked upwardlythrough the articles bythepart L when it rises. It will thus be seen that the part L operatesalternately in rotative and reciprocating vertical movements.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
